    Endopyelotomy, a minimally invasive procedure, effectively treated ureteropelvic junction obstruction in 87% of patients. This technique offers a less invasive alternative to open surgery with faster recovery.

    Area of Science:

    • Urology
    • Minimally Invasive Surgery
    • Nephrology

    Background:

    • Ureteropelvic junction (UPJ) obstruction is a common cause of upper urinary tract obstruction.
    • Traditional open pyeloplasty is effective but associated with significant morbidity and prolonged recovery.

    Purpose of the Study:

    • To evaluate the efficacy and outcomes of percutaneous endopyelotomy for UPJ obstruction.

    Main Methods:

    • Percutaneous full-thickness incision and stenting of the ureteropelvic junction (endopyelotomy) were performed in 38 patients.
    • Key procedural steps included proper placement of the nephrostomy tract and guidewire manipulation across the UPJ.

    Main Results:

    • Successful relief of obstruction was achieved in 33 (87%) of the 38 patients.

  • Endopyelotomy demonstrated excellent results, particularly for shorter UPJ lesions.

    • Conclusions:

    • Percutaneous endopyelotomy is a highly effective treatment for UPJ obstruction.
    • It offers a less morbid and faster recovery option compared to open pyeloplasty for select patient groups.
